Rumination Focus Cognitive Behavior Therapy

West University of Timisoara90 enrolled

Overview

1. To investigate the efficacy and acceptability of a guided internet-delivered transdiagnostic intervention targeting repetitive negative thinking for individuals with elevated levels of depression and generalized anxiety disorder (mild to moderate clinical symptoms) vs a wait-list control group (WLCG). 2. To investigate the hypothesized mechanism of change: Repetitive negative thinking is reduced first, and consequently the clinical symptoms (depression and/or anxiety) decrease.

The effectiveness of a Rumination Focused Cognitive-Behavioral Treatment (RF-CBT) will be compared with a wait list control group using a randomized control trial (RCT) design in a culture where this has not been tested before. The treatment approach was design to specifically target repetitive negative thinking (e.g., rumination and worries). Specifically, the treatment involves first a functional analysis design to help participants identify when rumination starts, distinguish between helpful versus unhelpful repetitive thinking, and learn more functional responses, and experiential and imagery exercises design to help them shift their thought processing towards concreteness, absorption and compassion. The main goal of the study is to test the effectiveness of this transdiagnostic approach in reducing symptom of depression and anxiety.

Outcomes

Primary Outcomes

Rumination Response Scale -10 items (RRS10)

The Rumination Response Scale -10 items (RRS10) was designed to measure participant's level of rumination. The scale has two subscale: Reflection (5 items) and Brooding (5 items). The score for each subscale ranges from 5 to 20, while the total score ranges from 10 to 40. Low scores are associated with low levels of rumination, while high scores are associated with high levels of rumination.

Time frame: Absolute values (average score) of RRS10 subscales (Reflection and Brooding) at 8 weeks (post-intervention)

Perseverative Thinking Questionnaire (PTQ)

Perseverative Thinking Questionnaire (PTQ) was designed to measure participant's level of rumination. The scale is unidimensional and the total score ranges from 0 to 60. Low scores are associated with low levels of rumination, while high scores are associated with high levels of rumination.

Time frame: Absolute values (average score) of PTQ at 8 weeks (post-intervention)

Patient Health Questionnaire 9 (PHQ9)

The Patient Health Questionnaire 9 (PHQ9) was designed to measure participant's level of depression. The scale is unidimensional and the total score ranges from 0 to 27. Low scores are associated with low levels of depression, while high scores are associated with high levels of depression.

Time frame: Absolute values (average score) of PHQ9 at 8 weeks (post-intervention)

Generalized Anxiety Disorder 7 (GAD7)

Generalized Anxiety Disorder 7 (GAD7) was designed to measure participant's level of generalized anxiety or worry. The scale is unidimensional and the total score ranges from 0 to 21. Low scores are associated with low levels of worry, while high scores are associated with high levels of worry.

Time frame: Absolute values (average score) of GAD7 at 8 weeks (post-intervention)

Social Phobia Inventory (SPIN)

The SPIN was designed to measure participant's level of social phobia. The scale is unidimensional and the total score ranges from 0 to 68. Low scores are associated with low levels of social phobia, while high scores are associated with high levels of social phobia.

Time frame: Absolute values (average score) of SPIN at 8 weeks (post-intervention)

Anxiety Sensitivity Index 16 (ASI16)

ASI16 was designed to measure participant's level of anxiety sensitivity. The scale is unidimensional and the total score ranges from 0 to 64. Low scores are associated with low levels of anxiety sensitivity, while high scores are associated with high levels of anxiety sensitivity.

Time frame: Absolute values (average score) of ASI at 8 weeks (post-intervention)

Secondary Outcomes

Work and Social Adjustment Scale (WSAS)

Work and Social Adjustment Scale (WSAS) was designed to measure symptom interference. The scale is unidimensional and the total score ranges from 0 to 40. Low scores are associated with higher levels of functioning (less interference of clinical symptoms) while high scores are associated with lower levels of functioning (or high interference of clinical symptoms).

Time frame: Absolute values (average score) of WSAS at 8 weeks (post-intervention)

Beck Depression Inventory-II (BDI-II)

The Beck Depression Inventory-II (BDI-II) was designed to measure participant's level of depression. The scale is unidimensional and the total score ranges from 0 to 63. Low scores are associated with low levels of depression, while high scores are associated with high levels of depression.

Time frame: Absolute values (average score) of BDI-II at 8 weeks (post-intervention)

Penn State Worry Questionnaire (PSWQ)

The PSWQ was designed to measure participant's level of generalized anxiety or worry. The scale is unidimensional and the total score ranges from 16 to 80. Low scores are associated with low levels of worry, while high scores are associated with high levels of worry.

Time frame: Absolute values (average score) of PSWQ at 8 weeks (post-intervention)
